You are blind in this short horror prototype, and must find your way around solely using your sense of sound. You may complete this game with your eyes closed.
That was a fairly unique concept; I've never really seen anything quite like that before. It reminded me of Minesweeper in several ways – particularly a spin-off called “Mine Tower” for the timed levels. The single biggest issue I had with the game was the difficulty, specifically with the timed levels. With level 4 , I had to play it around 10 times to beat, and I only did that on the very last second of the timer. And then level 6 … it took me at least 30 tries to beat it. It almost feels entirely luck based, because if I need to move back even one space, then it’s pretty much game over, as there is such a time crunch. It’s even worse because the paths you need to take often wind around and are hard to predict.
I eventually got to level 9 and then lost interest after trying it a few times. That made me realize that your game was dabbling in two different genres, without committing to either or melding them together in a feasible way. Level 6 did not really feel like a puzzle at all; rather, it was more like a twitch-reflex arcade game, as when deciding which triangular tile you should go to next, you’d have at most two different options. However, level 9 had a totally different feel, as you could have as many as 5 different tiles to choose from, which made it feels like a bit more of a traditional maze, though on an unrealistically short timer slapped on it. The “backspace penalty” does not make sense on the timed levels, as if you need to use it more than three times, you are unlikely to even finish the level in the first place with such a tight time restriction.
So I’d say either try dedicating to a slower-paced game by removing the timer and adding some more depth to it (I’d recommend looking at Minesweeper for inspiration), or a faster-paced game that only uses triangular tiles and adds a 5 or 10 more seconds to the clock (as well as maybe a keyboard button to go back a space, as every second counts). If you want to try and combine the these two, you could make it so players can look around the level beforehand to start getting an idea of what path they might need to take (possibly adding a single space on the map that is yellow, with players knowing that it will always come up one as a space they need to move to next). There is a lot of room for improvement here, though based on how many times I’ve gone back to try the levels over and over again (level 6 in particular), it must have something good going for it that kept pulling me back in : )
